MK48 ADCAP with UUV HF function?
 

How to add the UUV HF function on MK48 ADCAP?
I try to select the feedback option in object dialog, but when I enable the active mk48, it can't lock the target so it will create a new sierra in every second. even though only have one target sub/decoy at all

So, Is that no way to fix it?
I think mk48 ADCAP, mod 6 or 7 should be added the feedback function like uuv .
